long-chain quaternary ammonium hydroxides were synthesized from tertiary amines and confirmed by 1 H NMR and FTIR. Surface properties and pH of these surfactants were investigated. The critical micelle concentrations (CMC) of the synthesized quaternary ammonium hydroxides are lower than the conventional quaternary ammonium surfactants. The micelles shapes of these long-chain quaternary ammonium hydroxides
摘要由叔胺合成了一系列长链季铵氢氧化物,并通过1 H NMR和FTIR进行了证实。研究了这些表面活性剂的表面性质和pH。合成的季铵氢氧化物的临界胶束浓度(CMC)低于常规的季铵表面活性剂。这些长链季铵氢氧化物在水溶液中的胶束形状为球形,浓度为0.1 mol / L。合成的季铵氢氧化物的pH值为12.25–12.51。
